Connected DELTA DOP-B HMI with Arduino MEGA2560 as My arduino is Master. what should I do now? any hints as such as to what might be at fault? Next Generation SCADA System development with Arduino microcontroller and PLC. I'm like at the dead end, as function 3 is implemented on the same setting.

Delta hmi with arduino software#
I want to send anydata from arduino uno to HMI through RS-232 using UART communication.for that HMI ,DOPSoft software downloaded.we can desigh basic GUI screens.BUT i dont know how to. You might be guessing then whats left.ģ] master doesn't receive the reply :smiley-eek:Ĥ] also the master request lasts for about 1 second only and during this period the slave responds too (observed by RX and TX led blinking on the USB TO RS232 cable). Delta HMI communication with arduino atleaset led on off.

Here's the problem observed.ġ] master arduino sends the desired request (checked)Ģ] slave software processes the request and sends the correct reply (checked). I am using MODBUS slave simulator on laptop (interfaced arduino using USB TO RS232) to observe the packets. To guarantee our continued success we will achieve a reasonable profit, continue to be the leader in our industry through individual and combined dedication, innovation, and integrity. So now I tweaked the code to implement function 1 to read 16 points or coils. Our vision is that to provide the highest-quality end products to our customers, while striving to make them the leaders in their respective industries. I am interfacing delta HMI with arduino mega (serial 3 for MODBUS) implementing using MODBUS master library (baud 19200, 8 bit even parity 1 stop bit, 1000ms timout, retry count 10, polling rate 10ms) and alas it is working fine (read holding registers and working fine).
